IMPROVEMENT lN STILLS. FOR PETRQLEUM- AND OTHER OILS.

The Schedule referred. to in these Letter! Patent and making part of the some.

.I' SAMUEL VAN SYCKEL, of Titusville in the county of Crawford and State of Pennsylvania, have invented certain newand useful Improvements in Stills for Refining Oil, of which the followinu is a specification.

Nature and Objects of the-Invention.

My invention relates to stills for refining oil, and consists .in certain combinations and arrangements of part \\"ith an oil-still, the object of which is to greatly iaciitate the refining of the oil, as will be fully set forth hereafter.

The drawing accompanying thisspecification shows a'still and furnace, .with a portion of the side of the former broken away to show the arrangement of the.

interior.

7 General Description. 7

The still B and furnace A are constructed in the ordinary manner, and the dome preferably of triangular form, is connected with the still, as shown in the' drawing.

' At or near the center of the still, and from the inteiior of the dome, I suspend a series of pipes, d' d,

,t'rom the pipe D, connected with the steam-boiler, soinewhat resembling a gas-chandelier. -lhe ends or surfaces of these pipes d are perforated, so that jets of steam may .be thrown through them into the vapor above the surface of the. oil.

, The dome (J is for the purpose of conducting the lighter vapors to the pipes connecting with the worm, as they, rising first, will fill the dome and l eep the .lIoavier ones from the conducting-pipes 0 until the steam-jets act upon them.

In producing burning-oils from the crude oil, as J2lll;ttl t, West "irgini'afi and others, in which the. percentage of oil suitable for burningis low, great 'llt'llli is required in the furnace, and the chief-difiicnlty isflto obtain a light-colored oil at the high temperature it is necessary to keep the still. If, for instance, a still be filled with crude oil up to the level of the line my, and the fire started, the first oil produced will be light-colored, but, as the heat increases, the

-0il-vapor will become heavier and discolored.

11' at this pointjets otsl'cam are introduced through thcpipcs (l (linto the heated vapor, the temperature of the latter willtbe instantly reduced by the lower temperature of the steam, the heavier vapor will fall and give place to the lighter, and the 01! run from the still will be of the desired color. A

The temperature of the still can be regulated the quantity of steam admitted, and the great ad- 'vantage derived from its use, in additionto its .im-f proving, the quality of the oil, is that the' contents of the still canbe runoff in much less time than in the common way of attempting -to regulate the temperature of the still by the tires, a very dilficnlt method,

of producing a light-colored oil.

lhe steam readily passes ofi with the vaporfint'o the worm, and is condensed.

The oil produced by this process will stand a much 7 better fire-test, as the higher the temperature at which the oil is dlStlll6(l,tll6 more gas there will be int-he oil, and'the steam, acting to reduce the temperature of the vapor, will keep down the gaseous products.

In the usual mode of distilling, the stills are run down to five or six per cent. of their contents, when the fires are extinguished, and the stills left to cool. In thisfresidue of tar and other heavier products from the citude oil, there will be a portion of oil remaining, which it is ordinarily impossible to distil without increasing the heat and injuring the stills;

but by introducing steam I am enabled to remove a considerable portion of this oil from the refuse, without the aid of further heat from the furnace.

I claim as my invention I 1. The combination, with the still B, of the steamehandeller 1),"for introducing steam into the vapor of an oil-still, substantially in the purposes described and specified.

2. The combination, with the still B, of the dome O and the steam-chandelier D, all constructed substautially in the manner herein described and-specifled SAMUEL VAN SYOKEL.
